EXERCISE 2 Organ Systems Overview Time Allotment: 1½ hours (rat dissection—1 hour; human torso model—½ hour).

Solutions: Bleach Solution, 10% Measure out 100 milliliters of household bleach. Add water to a final volume of 1 liter.

Multimedia Resources: See Appendix B for Guide to Multimedia Resource Distributors.

Laboratory Materials Ordering information is based on a lab size of 24 students, working in groups of 2 or 4. A list of supply house addresses appears in Appendix A. Dissectible human torso model or cadaver 6–12 forceps 6–12 scissors 6–12 blunt probes

Disposable gloves, soap, and sponges 6–12 freshly killed or preserved rats, or predissected human cadaver

Twine or large dissecting pins 6–12 dissecting trays Lab disinfectant or 10% bleach solution

Advance Preparation 1. Make arrangements for appropriate storage and disposal of dissection materials. Check with the Department of Health or the Department of Environmental Protection, or their counterparts, for state regulations.

2. Designate a disposal container for organic debris, set up a dishwashing area with hot soapy water and sponges, and provide lab disinfectant such as Wavicide-01 (Carolina) or a 10% bleach solution for washing down the lab benches.

3. Set out safety glasses and disposable gloves for dissection of freshly killed animals (to protect students from parasites) and for dissection of preserved animals.

4. Decide on the number of students in each dissecting group (a maximum of four is suggested; two is probably best). Each dissecting group should have a dissecting pan, dissecting pins, scissors, blunt probe, forceps, twine, and a preserved or freshly killed rat.

5. Preserved rats are more convenient to use unless small mammal facilities are available. If live rats are used, they may be killed a half-hour or so prior to the lab by administering an overdose of ether or chloroform. To do this, remove each rat from its cage, and hold it firmly by the skin at the back of its neck. Put the rat in a container with cotton soaked in ether or chloroform. Seal the jar tightly, and wait until the rat ceases to breathe.

6. Set out human torso models and a dissected human cadaver if available.

Comments and Pitfalls 1. Students may be overly enthusiastic when using the scalpel and cut away organs they are supposed to locate and identify. Have blunt probes available as the major dissecting tool, and suggest that the scalpel be used to cut only when everyone in the group agrees that the cut is correct.

2. Be sure the lab is well ventilated, and encourage students to take fresh air breaks if the preservative fumes are strong. If the dissection animal will be used only once, it can be rinsed to remove most of the excess preservative.

3. Organic debris may end up in the sinks, clogging the drains. Remind the students to dispose of all dissection materials in the designated container.

4. The inferior vena cava and aorta may be difficult to distinguish in uninjected specimens.

Answers to Activity Questions Activity 5: Examining the Human Torso Model (pp. 23–24) 2. From top to bottom, the organs pointed out on the torso model are: brain, thyroid gland, trachea, lung, heart, diaphragm, liver, stomach, spleen, large intestine, greater omentum, small intestine 3. Dorsal body cavity: brain, spinal cord Thoracic cavity: aortic arch, bronchi, descending aorta (thoracic region), esophagus, heart, inferior vena cava, lungs, and trachea Abdominopelvic cavity: adrenal gland, descending aorta (abdominal region), greater omentum, inferior vena cava, kidneys, large intestine, liver, pancreas, rectum, small intestine, spleen, stomach, ureters, and urinary bladder Note: The diaphragm separates the thoracic cavity from the abdominopelvic cavity.

Right upper quadrant: right adrenal gland, right kidney, large and small intestine, liver, pancreas, stomach, right ureter Left upper quadrant: left adrenal gland, descending aorta, greater omentum, left kidney, large and 9

small intestine, pancreas, spleen, stomach, left ureter Right lower quadrant: large and small intestine, rectum, right ureter, urinary bladder Left lower quadrant: descending aorta, greater omentum, large and small intestine, left ureter, urinary bladder 4. Umbilical region: small intestine, large intestine, greater omentum Epigastric region: stomach, liver, small and large intestine, pancreas Hypogastric region: small and large intestine (including rectum) and urinary bladder Right iliac region: large intestine, small intestine, greater omentum, and right ureter Left iliac region: large intestine, small intestine, greater omentum, and left ureter Right lumbar region: large and small intestine, right kidney, right adrenal gland, and right ureter Left lumbar region: large and small intestine, left kidney, left adrenal gland, and left ureter Right hypochondriac region: liver Left hypochondriac region: stomach, spleen, pancreas Digestive: esophagus, liver, stomach, pancreas, small intestine, large intestine (including rectum) Urinary: kidneys, ureters, urinary bladder Cardiovascular: aortic arch, heart, descending aorta, inferior vena cava Endocrine: pancreas, adrenal gland, thyroid gland Reproductive: none Respiratory: lungs, bronchi, trachea Lymphatic/immune: spleen Nervous: brain, spinal cord

Answer to Group Challenge: Odd Organ Out (p. 24) Some possible answers to the questions are listed below. Student answers may vary.

1. Which is the “odd organ”?

Why is it the odd one out?

Stomach Teeth Small intestine Oral cavity

The teeth are an accessory structure of the digestive system, whereas the oral cavity, stomach, and small intestine are part of the digestive tract.

2. Which is the “odd organ”?

Why is it the odd one out?

Thyroid gland Thymus Spleen Lymph nodes

The thyroid gland is not an organ of the lymphatic system.

10

3. Which is the “odd organ”?

Why is it the odd one out?

Ovaries Prostate gland Uterus Uterine tubes

The prostate gland is not a part of the female reproductive system.

4. Which is the “odd organ”?

Why is it the odd one out?

Stomach Small intestine Esophagus Large intestine

The esophagus is in the thorax, whereas the stomach, small intestine, and large intestine are in the abdominopelvic cavity.
